Chapter 17. Customizing Kubernetes - API and Plugins
In this chapter, we will dig deep into the guts of Kubernetes. We will start with the Kubernetes API and learn how to work with Kubernetes programmatically via direct access to the API, the Python client, and then we will automate Kubectl. Then, we'll look into extending the Kubernetes API with custom resources. The last part is all about the various plugins Kubernetes supports. Many aspects of the Kubernetes operation are modular and designed for extension. We will examine several types of plugins, such as custom schedulers, authorization, admission control, custom metrics, and volumes. Finally, we'll look into extending Kubectl and adding your own commands.
The topics we cover are as follows:
- Working with the Kubernetes API
- Extending the Kubernetes API
- Writing Kubernetes and Kubectl plugins
- Writing webhooks
